MACHINE FOR CLEANING, OPENING, AND COMBING COTTON, COTTON WASTE, ANDLIKE MATERIALS.

Application filed November 2, 1926, Serial No. 145,882, and in GreatBritain October 16, 1926.

This invention relates to improvements in machines for opening, cleaningand comb ng cotton, cotton waste and similar materials of the type inwhich the fibres are fed to a licker-in roller from which they are drawnby suction through a duct to a revolving perforated cylinder which hascertain parts blanked off or provided with a guard so that the cylinderis not acted on by the suction at suchparts to allow the fibresdeposited on the cylinder to fall or be removed therefrom.

According to the present invention a casing havingsaw teeth is arrangedabove the licker-in roller and a second clearing roller where suchisemployed and also below the second clearer roller.

The invention will be described with reference to the accompanyingdrawings in which,

Fig. 1 is a side view of the machine.

Fig. 2 is a plan of same.

Fig. 3 is a longitudinal section.

Fig. 4 is a detail view of the casing of the licker-in roller.

The machine is constructed with a travelling feed lattice A whichdelivers the fibres to the feed rollers a which deliver them tothelicker-in roller B which is covered with wire clothing Garnett teeth orthe like. A second cleaning roller C is arranged behind the licker-inroller B between the latter and the duct D leading to the chamber E inwhich the perforated drum or cylinder F is mounted. The roller C iscovered with wire clothing, Garnett teeth or the like.

A roller B also covered with wire c1othing or Garnett teeth is mountedbelow the licker-in roller B and acts on the fibres to clean andstraighten them as they are carried round on the roller B. A furtherroller C similarly covered with wire clothing or Garnett teeth isarranged belowand between the rollers B and G and which roller has afurther cleaning and straightening action on the fibres.

A casing G is arranged over the top of the rollers B and C and isprovided on its underside with saw teeth 9 preferably inclined inopposition to the wires or teeth on the rollers B and C. A similarcasing G is arranged below the rollers C and C a space I) being leftbetween the casing Gr and the roller B The portion of the casing G belowthe roller C is provided with saw teeth on its inner face, the teeth gbeing inclined in-opposiare carried round by the rollers Band C.

The teeth 9 and g may be fixed or they may be. adjustable so thatthedistance between their points and the wires or teeth on the rollers Band C can be altered so as to suit different conditions andtypes offibres. To make the teeth adjustable they may be carried on suitableframes or flats g as shown in Fig. 4 and moved in relation to the casingby screws 9 A fixed plate A is arranged between the feed rollers a andthe licker-in roller B and this plate serves to remove any heavy matterfrom the fibres before the latter pass to the second roller C.Furthermore, any dirt or foreign matter removed by the roller B isdischarged through the gap 1) at the end of the bottom casing G A fan His mounted in the frame of the machine above the chamber E in which theperforated drum F is mounted and this fan is connected by the ducts hwith the interior of the perforated cylinder or drum F and produces thesuction necessary to convey the fibres along the duct D to the surfaceof the cylinder or drum F. An adjustable segment 7 pivoted about theshaft f on which the drum F is mounted is arranged inside the drum F tomask a portion of the surface thereof so that as the drum rotates thefibres can be removed from the surface thereof as they pass over themasked portion.

The fibres are delivered from the masked portion of the drum or cylinderon to a travelling lattice K which delivers them to the rollers Z of thecoiler mechanism L.

The different parts of the machine are driven from the fast and loosepulley M in the usual way through suitable gearing and/or belt, rope andchain drives.

What I claim as my invention and desire to protectby Letters Patentis 1. A machine of the type referred to for opening, cleaning andcombing cotton waste and similar material comprising in its constructionthe combination with a feed device of a licker-in roller to receive thefibres from the feed device, a second cleaning roller behind thelicker-in roller, a straightening roller below the licker-in roller, asec- 0nd straightening roller between and below the licker-in roller andthe second cleaning roller, a casing above the licker-in roller and thesecond roller, saw teeth on the sur- I face of said casing adjacent tothe rollers,a casing below the second cleaning roller and saw teethonthe surface of said casing adjacent to the roller.

2. A machine of the type referred to for opening, cleaning and combingcotton waste and similar material comprising in its con- "cotton wasteand similar materialcompris roller and'a fixed plate in struction thecombination with a feed device, of a licker-in roller to receive thefibres from the feed device, a second cleaning roller behind thelickei'in roller, a straightening roller below the licker-inlroller asecond;-

straightening roller between and below the licker in roller and thesecond cleaning roller, a casing above. the licker-in-"rollerand thesecond roller,=sa-w teeth'on thesurface of said casing adjacent to therollers, afcasing below the second cleaning-roller Vsaw teeth on thesurface of saidcasing adjacent to the front oftthe lickerin roller.

3. In a machine of thetype referred to for opening, cleaning andcombing'cotton,

ing in its construction the combination of the following parts: a feedlattice, afpair of feed rollers,'a licker-in roller to receive thefibres from the feed rollers, a second cleanin' roller behind thelicker-in roller, a strai htening roller, in frontof and belowthe lieer-in'i'oller, a second straightening and the second cleaning roller,acasing above the licker-in roller and the second cleana suction in theperforateddrum, ducts con necting the fan to the interior of the drum, amasking device for cutting off the suction from a portion of theperiphery of the drum, a travelling lattice to receive thefibres fromthe drum and coilerj mechanism thelattice delivers the fibres. a

- roller between and below the licker-in roller m which f r In testimonywhereof lhave hereunto s et my hand.
